Huge parts of Mexico are in a major drought right now, so there's literally not enough water to go around. There is also a housing shortage in the cities (due to a lack of building new apartments, and due to the shortage of older tree-lined neighborhoods - as elsewhere, what's being built now is not enough and not so nice), and gentrification is creating an affordability issue. It's not dissimilar to the dissatisfaction in some US cities. Some of this is exacerbated by "digital nomads" who moved during COVID, but it's also due to longer term government issues very similar to what the US is facing.

Anyway, "Gringo go home" is not an uncommon phrase graffitied on walls. I'd love to move there, but I don't want to make life more difficult for locals, or be perceived as doing so.
